Developing a Daemon for Mac with Qt and C++

[coderqueen]

Hi,

I am trying to develop a dummy daemon for Mac OSX which should launch on startup and should support 'Stop,Resume, Pause'. For now, I have developed a code which is simply opening a text file and logging some data on it when the service starts. Unsure on how to stop it. Any advice on the best approach possible would be appreciated. Here is a little snippet.

@
void AppService::start()
{
try
{
QCoreApplication *app= application();
qDebug()<<"Service has started!";
qDebug()<< app->applicationDirPath();

    FILE *t;
    pid_t pid=0;
    pid_t sid=0;
    pid=fork();
    if (pid < 0) {
            exit(1);
    }
    if(pid>0)
    {
        std::cout<<"Service has started!";
        exit(0);
    }

    umask(0);
    sid=setsid();
    if(sid <0)
    {
        exit(1);
    }

    chdir("/");
    t=fopen&#40;"/Users/gecdelivery/projectfile/logfile.txt","w+"&#41;;


    close(STDIN_FILENO);
    close(STDOUT_FILENO);
    close(STDERR_FILENO);

    while(1){
    sleep(1);
    fprintf(t,"Service is running!\t Time %s\n",dt);
    fflush(t);
}
fclose(t);


}
